A single, five-day go-kart event could have a big financial impact on Camden and Kershaw County if the Carolina Motorsports Park (CMP) hosts a national race in 2014. CMP’s Brian Smith said that impact could be as much as $1.56 million, perhaps more. During a presentation Tuesday evening to Camden City Council, Smith said CMP is applying to host the 2014 U.S. Rotax Grand Nationals in August 2014.
